Quarrying and Mining

Environmental Monitoring for Quarrying and Mining

Quarries and mines present demanding monitoring conditions. Changing water levels, high pumping rates, sediment, difficult access and exposed locations can all influence how monitoring equipment should be selected, installed and maintained.

Flux Enviro provides equipment and monitoring solutions for groundwater, surface water, discharge, flow, water quality, rainfall and particulate monitoring, ranging from routine sampling and field measurements through to permanent monitoring installations and remotely connected multi-sensor networks.

Equipment can be supplied, rented or integrated into complete monitoring systems, with installation, commissioning, servicing and ongoing technical support available across the UK and Ireland.

Choosing the Right Monitoring Approach

Effective environmental monitoring rarely relies on a single method. Sampling, field measurement and continuous monitoring each provide different information, while telemetry improves how continuous data is accessed and managed. The appropriate combination depends on the monitoring objective, parameters, site conditions and regulatory requirements.

A laboratory sample provides a measurement at a particular point in time. Continuous monitoring helps show what happens between samples. Used together, they provide a more complete understanding of changing site conditions.

Groundwater Sampling & Monitoring

Groundwater monitoring can help establish baseline conditions, identify changes in groundwater levels and quality, assess potential environmental impacts, and understand the effects of quarry pumping and dewatering.

Monitoring requirements can range from routine sampling and manual water-level measurements through to pumping investigations, continuous level logging and remotely connected groundwater monitoring networks.

Flux Enviro provides equipment and monitoring solutions for:

• Groundwater sampling and low-flow purging, including pumps, bailers and dedicated sampling equipment

• Manual groundwater-level measurement for routine monitoring and verification

• Continuous groundwater level and temperature monitoring using pressure loggers and sensors

• Groundwater-quality measurement using handheld and multiparameter instrumentation

• Pumping and dewatering investigations, including monitoring groundwater response

• Long-term groundwater monitoring, with local logging or remote telemetry

• Sampling consumables and accessories, including tubing and filtration equipment

Systems can be developed around individual boreholes or extended across multi-location groundwater monitoring networks, allowing groundwater levels and other environmental measurements to be assessed alongside rainfall, quarry inflows, pumping and discharge data.

Surface Water, Discharge & Flow

Quarry drainage, settlement systems, outfalls and receiving waters can present very different hydraulic conditions. Flow range, water depth, velocity, sediment, channel or pipe geometry and access can all influence the most appropriate measurement method.

Flux Enviro provides equipment and monitoring solutions for:

• Surface water and discharge sampling

• Manual flow measurement and discharge surveys

• Continuous open-channel and pipe flow monitoring

• Area-velocity measurement

• Weirs and flumes

• Water level and stage monitoring

• Pumped discharge monitoring

• Settlement lagoons, outfalls and receiving waters

Measurement methods can include manual velocity measurement, pressure/stage, acoustic Doppler, ultrasonic, area-velocity and electromagnetic technologies, depending on the site conditions and monitoring objectives.

We can help determine the appropriate measurement location and method, then supply, install, commission and verify the instrumentation for temporary surveys or permanent monitoring.

Rainfall & Meteorological Monitoring

Local rainfall and meteorological data provide important context for understanding groundwater response, quarry inflows, lagoon levels, discharge rates, water-quality changes and particulate events.

Standalone or remotely connected monitoring systems can measure:

• Rainfall

• Air temperature and relative humidity

• Barometric pressure

• Wind speed and direction

• Solar radiation

Rainfall data can be monitored alongside groundwater levels, surface water, flow and discharge, helping to understand how site conditions respond to individual rainfall events and longer-term changes.

Meteorological measurements can also support site operations. Wind speed and direction, for example, can provide context for particulate events or be used to establish operational thresholds for activities such as tipping.

Continuous Particulate Monitoring

Traditional deposited-dust methods such as the Bergerhoff method provide a time-integrated measure of dust deposition, but offer limited information about when an event occurred, how long it lasted, its intensity, or the conditions associated with it. This can significantly limit their usefulness when investigating short-duration particulate events or relating measurements to specific site activities.

Continuous particulate monitoring provides much greater temporal resolution, allowing changes and individual events to be identified as they occur and compared with site operations and meteorological conditions.

Systems are available for:

• PM₁₀ and PM₂.₅

• Total suspended particulate (TSP)

• Site boundary and sensitive receptor monitoring

• Wind speed and direction

• Remote data access

• Configurable alarms

When combined with meteorological monitoring, particulate concentrations can be assessed alongside wind speed and direction, providing considerably greater context when investigating individual events and potential emission sources.

Remote Monitoring & Telemetry

Telemetry connects individual instruments and monitoring locations into a common system, providing continuous visibility of site conditions without relying on routine visits to collect data. This can be particularly valuable across quarry and mining sites where monitoring locations are remote, access is difficult, conditions can change rapidly or environmental limits need to be demonstrated.

Remote monitoring can provide:

• Continuous data access – view current and historical measurements remotely

• Automated alarms and notifications – identify high water levels, changing discharge conditions, water-quality events or other defined thresholds

• Event capture – identify short-duration changes that may occur between routine site visits or sampling rounds

• Improved understanding of site response – compare rainfall, groundwater, discharge, flow and water-quality data to identify relationships between changing conditions

• Operational insight – use monitoring data to inform pumping, water management, settlement systems and other site activities

Systems can range from individual telemetered instruments to multi-sensor stations and site-wide monitoring networks. Water level, flow, water quality, rainfall, meteorological and other compatible sensors can be integrated within a common data platform, providing a more complete picture of changing site conditions.

Quarry Monitoring Experience

Flux Enviro supports several of the largest quarry operators across Ireland, alongside independent operators, environmental consultants and contractors. Our team has practical experience delivering monitoring solutions across operational quarries and sites undergoing restoration, from individual monitoring points through to integrated multi-sensor telemetry networks.

Examples include:

• Retrofitting water-level sensors to existing weir discharge chambers

• Continuous water-quality monitoring of quarry discharge

• Continuous upstream and downstream turbidity monitoring

• Continuous discharge flow monitoring

• Multi-location perimeter groundwater monitoring networks

• Integrated meteorological, groundwater, surface-water, flow and water-quality monitoring systems

For permanent installations, Flux Enviro can support the complete monitoring system, considering measurement location, sensor installation, power, communications, physical protection, maintenance access and long-term data requirements.
